Abundant on the saline flats about Canon City (Brandegee). — This 

 common New Mexican species is thus shown to extend into Southern 

 Colorado. It is a prostrate annual, readily known by its pubescence, 

 which extends to the sharp angled capsule. It has rounded, subcordate, 

 sharply serrate leaves; lateral, leafy, crowded racemes, with very small 

 and slender long-iieduncled, involucres and slender sharply -i-angled rugose- 

 dotted seeds, which are about as long as the involucre itself (about 0.6 

 lines long). The styles are short and undivided. — Geo. Engel^iann.

Originally sparingly collected without fruit on the-Eio Grande, near 

 EI Paso, by Charles Wright. 



This species, as it now proves to be, was abundantly seen on the sandy 

 flats of the San Juan Kiver, in Southwestern Colorado, by Mr. Bran- 

 degee, where it occurs with the allied E. petaloidea, but unfortunately it 

 seemed to be too common to make specimens of! 



Stems 6-12 inches long; leaves 6-9 lines long, ^ to 1 line wide; involu- 

 cres about f line wide ; seeds of same length. — Readily distinguished 

 from the allied E.petaloidea by the smaller involucre bearing very small 

 and almost naked glands, often less than four in number, the more nu- 

 merous stamens (often up to 25) with much smaller anthers, and by the 

 smaller, more angular and more pointed, grayish seeds, while those of 

 the allied species are larger, thicker, with rounded angles, and of a more 

 reddish color. — Geo. Engelma>'N.
